The main control unit 11 includes a CPU (Central Processing Unit) and performs various arithmetic processes.

The storage unit 12 is a volatile RAM (Random Access Memory), a nonvolatile ROM (Read Only Memory), a hard disk drive, a flash memory, and the like. Various programs and information supplied from the banknote depositing and dispensing machine 10 are various. The information is memorized. The communication unit 13 is connected to the banknote control unit 21 of the banknote depositing / dispensing machine 10, and transmits / receives various information to / from the banknote control unit 21. The main control unit 11 reads various programs from the hard disk drive or the like of the storage unit 12 and performs various processes such as a deposit process and a withdrawal process while using a RAM or the like as a work area.

As shown in the side view of FIG. 3, the banknote depositing and dispensing machine 10 includes a banknote control unit 21, a depositing / dispensing unit 22, a transport unit 23, a discrimination unit 24, a temporary storage unit 25, a plurality of banknote storage units 26, and a reject storage unit. 27 is provided. The banknote control unit 21 includes a CPU, like the main control unit 11, and performs various processes such as a process of controlling the operation of each unit by reading and executing a predetermined program from a ROM or a flash memory. Moreover, the banknote control part 21 memorize | stores various information in the memory | storage part which has inside.

The deposit / withdrawal unit 22 separates the banknotes received from the customer one by one and delivers them to the transport unit 23, and accumulates the banknotes transported from the transport unit 23 and causes the customer to receive them. The conveyance part 23 conveys a banknote along the conveyance path where the conveyance guide which guides a banknote, many rotating rollers, etc. are arrange | positioned suitably.

The discriminating unit 24 is arranged along the bill conveyance path, and the type, authenticity, correctness (whether it is damaged), or the like of the bill to be conveyed by a plurality of types of sensors incorporated therein. And the discrimination result is sent to the banknote control unit 21 (details will be described later). The temporary storage unit 25 temporarily stores the banknotes transported by the transport unit 23, and pays out the banknotes and delivers them to the transport unit 23.

When the banknote storage 26 is transported by the transport unit 23 according to the denomination, the banknote 26 is judged that the degree of damage is small and can be reused by the discrimination unit 24 and the banknote control unit 21. Banknotes are collected and stored inside. Moreover, if the banknote storage 26 receives the instruction | indication which pays out a banknote from the banknote control part 21, it will separate | stack the banknote currently accumulated | stacked one by one and will deliver it to the conveyance part 23.

When the banknote control unit 21 determines that the banknote control unit 21 should not reuse the banknote (so-called reject banknote) based on the discrimination result by the discrimination unit 24, the reject box 27 is transported by the transport unit 23. The bill is stored inside.

For example, when a customer performs a deposit transaction with the automatic teller machine 1, the banknote control unit 21 receives a predetermined operation input via the operation display unit 6 in cooperation with the main control unit 11 and the like. The shutter of the deposit / withdrawal port 5 (FIG. 1) is opened, and a bill is inserted into the deposit / withdrawal unit 22. When a banknote is inserted, the deposit / withdrawal unit 22 closes the shutter of the deposit / withdrawal port 5, separates the banknotes one by one, and delivers them to the transport unit 23. The conveyance part 23 conveys the received banknote, makes it discriminate by the discrimination part 24, and notifies the banknote control part 21 of the obtained discrimination result. In response to this, the banknote control unit 21 determines the transport destination of each banknote.

At this time, the transport unit 23 transports the banknotes identified as normal in the discrimination unit 24 (so-called correct bills) to the temporary storage unit 25 and temporarily holds them, while banknotes identified as not to be traded (so-called damages). A ticket, a fake ticket, etc., which is also called a reject banknote) is conveyed to the deposit / withdrawal unit 22 and returned to the customer.

Subsequently, the banknote control unit 21 transports and stores the banknote as a reject banknote that should not be reused if the banknote is damaged, and reuses the banknote if the damage is small. The bills to be conveyed are conveyed and stored in the bill storage 26 corresponding to the denomination.

On the other hand, for example, when a customer performs a withdrawal transaction with the automatic teller machine 1, the bill control unit 21 cooperates with the main control unit 11 and the like via the operation display unit 6 (FIG. 1). After accepting the operation input, the banknote corresponding to the amount to be withdrawn is fed out from the banknote storage 26. Subsequently, the banknote control unit 21 conveys the banknote to the discrimination unit 24 by the transport unit 23 and then performs the discrimination, and then transports the banknote to the deposit / withdrawal unit 22 and opens the shutter of the deposit / withdrawal port 5 (FIG. 1). Let the customer take it out.

[2. Configuration of identification unit]
As shown in the left side view of FIG. 4, in the discrimination unit 24, a plurality of components are arranged along the upper conveyance guide 30A and the lower conveyance guide 30B penetrating in the front-rear direction. The upper conveyance guide 30A and the lower conveyance guide 30B are each formed in a single thin plate shape in the vertical direction.

The upper conveyance guide 30A and the lower conveyance guide 30B (hereinafter collectively referred to as the conveyance guide 30) have a relatively narrow gap in the vertical direction with the lower surface of the upper conveyance guide 30A and the upper surface of the lower conveyance guide 30B facing each other. (Hereinafter, this is referred to as a conveyance path W). The transport path W is formed in a straight line along the front-rear direction. For this reason, the conveyance guide 30 guides the banknotes to advance along the conveyance path W.

A conveyance roller pair 32, a thickness sensor 33, a conveyance roller pair 34, an image sensor group 35, a conveyance roller pair 36, and a magnetic sensor are arranged in the vicinity of the conveyance guide 30 in the discrimination unit 24 along the conveyance path W from the rear side. 37 and a conveying roller pair 38 are disposed. In the discrimination unit 24, a motor 39 that generates a driving force and a discrimination control unit 40 that controls the inside of the discrimination unit 24 are provided.

The conveying roller pair 32 has a driven roller 32A and a driving roller 32B arranged on the upper and lower sides of the conveying path W facing each other. The driving roller 32B receives a driving force from the motor 39 through a transmission mechanism constituted by a gear or a belt, and rotates by this driving force. The driven roller 32A can freely rotate and is pressed against the driving roller 32B by a biasing member.

With this configuration, when the banknote is transported along the transport path W, the transport roller pair 32 holds the banknote between the driven roller 32A and the drive roller 32B. In this state, when the driving force is transmitted from the motor 39 to the driving roller 32 </ b> B, the conveying roller pair 32 conveys the driving force to the bills so as to be conveyed forward or backward along the conveying path W. The conveyance roller pairs 34, 36, and 38 are all configured in the same manner as the conveyance roller pair 32, and thus description thereof is omitted.

The thickness sensor 33 opposes the displacement roller 33A and the reference roller 33B disposed above and below the conveyance path W, respectively. Each of the displacement rollers 33A and the reference roller 33B is sufficiently shorter in the left-right direction than the long side of the bill. In the discrimination unit 24, for example, about ten displacement rollers 33A and reference rollers 33B are arranged in alignment along the left-right direction.

The reference roller 33B can freely rotate, and the distance with respect to the up-down direction, that is, the conveyance path W is not changed. The displacement roller 33A can freely rotate and is pressed against the reference roller 33B. Further, a displacement sensor that detects the displacement of the displacement roller 33A in the vertical direction is provided in the vicinity of the displacement roller 33A.

When the banknote is conveyed, the displacement roller 33A sandwiches the banknote with the reference roller 33B and is displaced upward by a displacement amount corresponding to the thickness of the banknote. At this time, the thickness sensor 33 detects the displacement amount of the displacement roller 33A by the displacement sensor, generates thickness information based on the displacement amount, and supplies the thickness information to the discrimination control unit 40 as a thickness detection result. The thickness sensor 33 detects the thickness of the banknote at a thickness detection point 33D that is the lowest point of the displacement roller 33A.

The image sensor group 35 includes an upper image sensor 35A and a lower image sensor 35B attached to the upper conveyance guide 30A and the lower conveyance guide 30B, respectively. The upper image sensor 35 </ b> A and the lower image sensor 35 </ b> B are line sensors, and each of the imaging elements formed linearly along the left-right direction is directed toward the conveyance path W side.

The upper image sensor 35A and the lower image sensor 35B capture both sides of the banknote transported on the transport path W one line at a time by the respective image sensors, respectively generate upper image information and lower image information as detection results, These are supplied to the discrimination control unit 40. Hereinafter, the locations where the imaging elements are arranged in each of the upper image sensor 35A and the lower image sensor 35B are referred to as an upper imaging point 35AD and a lower imaging point 35BD, respectively. The upper image information and the lower image information are sequentially connected along the transport direction, thereby forming a planar image obtained by imaging a banknote in a planar manner.

In the magnetic sensor 37, a magnetic module 37A is disposed on the upper side of the transport path W, and a support roller 37B is disposed on the lower side of the transport path W. When the banknote conveyed along the conveyance path W by the identification conveyance roller group is supported by the support roller 37B, the magnetic module 37A detects magnetism from the banknote, generates magnetic information representing the detection result, and performs identification control. Supply to unit 40. The magnetic sensor 37 detects the magnetism of the banknote at a magnetic detection point 37D on the surface on the transport path W side.

The motor 39 rotates under the control of the discrimination control unit 40, and the driving force is transmitted to the driving roller 32 </ b> B of the conveyance roller pair 32 by the transmission mechanism configured by a gear, a belt, and the like, and is rotated to the conveyance path W. A banknote is conveyed along. An encoder 39E is attached to the output shaft of the motor 39. The encoder 39E generates a pulse signal corresponding to the rotation amount of the motor 39 and supplies it to the discrimination control unit 40.

Incidentally, in the discrimination unit 24, as described above, the rotation of the motor 39 is transmitted to the drive roller 32B and the like of the transport roller pair 32 by the transmission mechanism, and the drive roller 32B and the like are rotated. Here, due to the nature of the transmission mechanism, the rotation of the motor 39 is always transmitted to the drive roller 32B and the like at a constant ratio.

Therefore, in the discrimination unit 24, a proportional relationship is established between the rotational speed of the motor 39 and the rotational speed of the drive roller 32B. Accordingly, the discrimination unit 24 also establishes a proportional relationship between the number of pulses in the pulse signal generated by the encoder 39E and the transport distance of the bills transported by the drive roller 32B or the like. Therefore, hereinafter, the distance that the bills are conveyed per pulse in the discrimination unit 24 is referred to as a pulse conveyance distance R [mm]. The pulse transport distance R can be obtained by calculation or actual measurement of a gear ratio or the like.

In the discrimination unit 24, the thickness sensor 33, the upper image sensor 35A, the lower image sensor 35B, and the magnetic sensor 37 (hereinafter collectively referred to as a discrimination sensor group) are fixed. ), The distances between the thickness detection point 33D, the upper imaging point 35AD, the lower imaging point 35BD, and the magnetic detection point 37D are also fixed.

Therefore, hereinafter, for convenience, the lower imaging point 35BD is regarded as a reference point, the front side is negative, the rear side is positive, and the distances from the lower imaging point 35BD to the upper imaging point 35AD, the magnetic detection point 37D, and the thickness detection point 33D are as follows. , Distances L2, L3, and L4 [mm], respectively. Further, by dividing the distances L2, L3, and L4 by the pulse transport distance R described above, the pulse distances PL2, PL3, and PL4 converted into the number of pulses detected by the encoder 39E can be obtained. The pulse distances PL2 and PL4 are positive values, and the pulse distance PL3 is a negative value.

As shown in FIG. 5, the discrimination control unit 40 includes a discrimination control unit 41, and a discrimination storage unit 42, a discrimination communication unit 43, a sensor control unit 44, and a drive control unit 45 are respectively connected to the discrimination control unit 41. It is connected to the. Similar to the main control unit 11 and the bill control unit 21 (FIG. 2), the discrimination control unit 41 includes a CPU, and reads out and executes a predetermined program from a ROM or a flash memory, thereby controlling the operation of each unit. Various processes are performed.

Like the storage unit 12 (FIG. 2), the discrimination storage unit 42 is a RAM, a ROM, a hard disk drive, a flash memory, or the like, and stores in advance pulse distances PL2, PL3, and PL4 in addition to various programs such as a discrimination program. In addition, the information supplied from each sensor is temporarily stored. The discrimination communication unit 43 is connected to the banknote control unit 21 and transmits and receives various information to and from the banknote control unit 21.

The sensor control unit 44 is connected to each sensor (upper image sensor 35A, lower image sensor 35B, magnetic sensor 37, and thickness sensor 33) of the discrimination sensor group, and information (upper image information) indicating a detection result from each sensor. , Lower image information, magnetic information, and thickness information) are acquired and delivered to the discrimination control unit 41.

The drive control unit 45 is connected to the motor 39, and rotates or stops at a desired speed by supplying a control signal to the motor 39. The drive control unit 45 is also connected to the encoder 39E, acquires a pulse signal from the encoder 39E, and supplies the pulse signal to the discrimination control unit 41. In response to this, the discrimination control unit 41 counts the number of pulses appearing in the pulse signal obtained from the encoder 39E, and holds the obtained value as a pulse count value.

Based on the control instruction supplied from the banknote control unit 21, the discrimination unit 24 always operates each sensor of the discrimination sensor group while conveying the banknotes in the transport unit 23 (FIG. 2), and represents the detection result. Are continuously acquired and stored in the discrimination storage unit 42. As shown in FIG. 6, a lower image information storage area 51, an upper image information storage area 52, a magnetic information storage area 53, a thickness information storage area 54, and four information storage areas are provided inside the discrimination storage section 42. It has been.

In the lower image information storage area 51, as in a general storage area, addresses that are continuous numerical values are sequentially assigned for each predetermined storage unit (for example, 1 byte). The discrimination storage unit 42 stores a lower image information storage address as an address when new image information for one line is stored in the lower image information storage area 51. In FIG. 6, it is assumed that the address value increases from top to bottom.

The identification control unit 41 increments the value of the lower image information storage address every time the pulse count value, that is, the number of pulses in the pulse signal obtained from the encoder 39E increases. Subsequently, the discrimination control unit 41 adds one line newly obtained from the lower image sensor 35B (FIGS. 4 and 5) to the location indicated by the increased lower image information storage address in the lower image information storage area 51. The lower image information is stored. For this reason, in the discrimination unit 24, each line constituting the lower image information is associated with the pulse count value via the address of the lower image information storage area 51. When the value of the lower image information storage address reaches the end address value of the lower image information storage area 51, the discrimination control unit 41 sequentially stores the latest information like a ring buffer by returning to the start address value. It has become.

The upper image information storage area 52, the magnetic information storage area 53, and the thickness information storage area 54 are all configured in the same manner as the lower image information storage area 51, and consecutive addresses are sequentially assigned to each storage unit. . In each information storage area, although absolute addresses in different ranges are assigned to each other so that the address values do not overlap each other, portions corresponding to each other can be specified by relative addresses.

In addition, as in the case of the lower image information storage area 51, the discrimination storage unit 42 stores new upper image information, magnetic information, and thickness information in the upper image information storage area 52, the magnetic information storage area 53, and the thickness information storage area 54, respectively. The upper image information storage address, magnetic information storage address, and thickness information storage address are stored as addresses for storage.

Each time the pulse count value increases, the discrimination control unit 41 increments the value of each information storage address, and obtains a new value from each sensor at the location indicated by each increased information storage address in each information storage area. Each one line of information (upper image information, magnetic information and thickness information) is stored. Therefore, in the discrimination unit 24, as in the case of the lower image information, the upper image information, the magnetic information, and the thickness information are also passed through the addresses of the upper image information storage area 52, the magnetic information storage area 53, and the thickness information storage area 54. Each line constituting each piece of information is associated with a pulse count value.

In the discrimination unit 24, only the lower image sensor 35B is disposed below the transport path W, and the other upper image sensor 35A, the magnetic sensor 37, and the thickness sensor 33 are disposed above the transport path W. For this reason, as shown in FIG. 6, the discrimination storage unit 42 has only the lower image information stored in the lower image information storage area 51, and the other upper image information, magnetic information, and thickness information are reversed left and right. Yes.

In the discrimination unit 24 (FIG. 4), a thickness sensor 33, an upper image sensor 35A, a lower image sensor 35B, and a magnetic sensor 37 are arranged at locations separated from each other along the conveyance path W. For this reason, when a certain banknote is sequentially identified by each sensor while being conveyed in the identification unit 24, the timing of generating information based on the same part (for example, the vicinity of the left rear apex) of the banknote is It is different for each sensor.

Therefore, in the discrimination unit 24, the pulse count values when the same portion of the banknote reaches each sensor are also different from each other. For this reason, as shown in FIG. 6, each information stored in each information storage area corresponding to each sensor has a different relative address representing the same part in the bill BL.

The discrimination control unit 41 executes discrimination processing using the obtained information (upper image information, lower image information, magnetic information, and thickness information), and the denomination, authenticity, degree of damage, etc., for the banknote being conveyed And the obtained discrimination result is notified to the banknote control unit 21 via the discrimination communication unit 43. Moreover, the discrimination control part 41 reads the serial number of a banknote by performing a predetermined character recognition process with respect to the obtained upper image information and lower image information, and notifies the banknote control part 21 of the read serial number.

Based on this, the banknote control part 21 determines the conveyance destination of each banknote, after determining the state (normal, a fake ticket, other than a banknote, etc.) of each banknote, and controls the conveyance part 23 (FIG. 3). Transport to that destination. Moreover, the banknote control part 21 memorize | stores the obtained serial number in the memory | storage part 12 (FIG. 2).

[3. Extraction and storage of identification information]
When the banknote control part 21 (FIG. 3) judges that the banknote inserted from the customer in a deposit transaction is a reject banknote, as above-mentioned, the conveyance part 23 etc. are controlled and this reject banknote is returned to a customer. At this time, the banknote control unit 21 instructs the discrimination unit 24 to store information (upper image information, lower image information, magnetic information, and thickness information) obtained from each sensor regarding the rejected banknote as reject banknote information.

In response to this, the discrimination control unit 41 (FIG. 5) of the discrimination unit 24 receives the lower image information and the upper image from the lower image information storage area 51, the upper image information storage area 52, the magnetic information storage area 53, and the thickness information storage area 54. Information, magnetic information and thickness information are read out and stored in a predetermined reject banknote information storage area.

At this time, the discrimination control unit 41 associates portions corresponding to each other with respect to the same portion of the banknote out of information stored in each information storage area, and cuts out and stores only a portion corresponding to the banknote. The discrimination control unit 41 reads and executes an information extraction program stored in advance in the discrimination storage unit 42, thereby starting an information extraction processing procedure RT1 shown in FIG. 7 and proceeds to step SP1.

In step SP1, the discrimination control unit 41 recognizes the range in which one banknote is captured and the position of each vertex from the lower image information stored in the lower image information storage area 51, and proceeds to the next step SP2. Move. At this time, the discrimination control unit 41 can recognize an approximate range of the banknote by performing, for example, a known image recognition process, and detects each side of the banknote by, for example, a known edge detection process, and uses this to detect each side of each vertex. The position can be recognized.

In step SP2, the discrimination control unit 41 sets a lower image cutout range Q1 (FIG. 6) as a range to be cut out from the lower image information of the lower image information storage area 51, and a lower image start address A1S that is the start address and end address thereof. The lower image end address A1E is determined, and the process proceeds to the next step SP3. Here, the lower image cutout range Q1 is set to a range slightly wider than the range including all the vertices recognized in step SP1.

In step SP3, the discrimination control unit 41 uses the lower imaging point 35BD of the lower image sensor 35B as a reference, the pulse distance PL2 to the upper imaging point 35AD of the upper image sensor 35A, and the pulse distance PL3 to the magnetic detection point 37D of the magnetic sensor 37. The pulse distance PL4 to the thickness detection point 33D of the thickness sensor 33 is read from the discrimination storage unit 42, and the process proceeds to the next step SP4.

In step SP4, the discrimination control unit 41 uses the lower image start address A1S, the lower image end address A1E, and the read pulse distances PL2 to PL4, respectively, to extract ranges from the upper image information, magnetic image information, and thickness image information. Is calculated, the respective start addresses and end addresses are calculated, and the process proceeds to the next step SP5.

The discrimination control unit 41 adds the upper image start address A2S and the upper image end address by adding the pulse distance PL2 representing the relative position of the upper imaging point 35AD to the lower image start address A1S and the lower image end address A1E, respectively. A2E (FIG. 6) is calculated respectively. The upper image start address A2S and the upper image end address A2E define an upper image cutout range Q2 (FIG. 6) that is a range cut out as a portion corresponding to a banknote with respect to the upper image information in the upper image information storage area 52. .

[4. Supply and display of identification information]
By the way, the customer who has received the reject banknote returned from the automatic teller machine 1 guesses the reason why the reject banknote is returned, that is, the reason that the banknote is determined to be abnormal by visual confirmation, and then other banknotes. Replace it with a new one and re-enter it. However, the customer may contact the staff of the financial institution if he / she does not understand the reason for determining the abnormality. The staff member who has received the inquiry from the customer makes a visual check by himself / herself, and if he / she does not understand the reason why the abnormality is determined, he / she operates the automatic teller machine 1 to refer to the discrimination result.

At this time, the main control unit 11 of the automatic teller machine 1 shifts to a predetermined staff operation mode according to the operation of the staff and displays a dedicated operation screen on the operation display section 6. The main control unit 11 receives information about rejected banknotes from the discrimination unit 24 of the banknote depositing / dispensing machine 10 by receiving a predetermined operation from the staff, for example, an operation of inputting the serial number of the banknote, as shown in FIG. A reject banknote information display screen D1 is displayed on the operation display unit 6.

On the reject banknote information display screen D1, four types of images based on the cut-down information T1, cut-out information T2, cut-out magnetic information T3, and cut-out thickness information T4 are aligned in the vertical and horizontal directions. Are arranged. In these four types of images, the relative positions of the portions corresponding to the banknotes in the respective frames coincide with each other. Further, on the reject banknote information display screen D1, the denominated money type, the read serial number, and the like are displayed as information on the reject banknote.

Further, on the reject banknote information display screen D1, four types of images based on the cut-down information T1, cut-out information T2, cut-out magnetic information T3, and cut-out thickness information T4 are determined as reject banknotes. Instruction frames C1, C2, C3, and C4 are displayed in an overlapping manner at the location where the abnormality that caused the error is detected. The staff guesses the reason why the banknote is determined to be abnormal by referring to the four types of images and the instruction frames displayed on the reject banknote information display screen D1, and explains to the customer.

[5. Effect]
In the above configuration, when there is a banknote (reject banknote) that is determined to be abnormal by the discrimination unit 24 of the banknote depositing and dispensing machine 10, the automatic teller machine 1 includes information obtained from each sensor of the discrimination unit 24. A portion corresponding to the banknote is cut out and stored.

At this time, the discrimination control unit 41 of the discrimination unit 24 first recognizes each vertex of the banknote in the lower image information stored in the lower image information storage area 51, sets the lower image cutout range Q1, and sets the pulse distance PL2˜ The upper image cutout range Q2, the magnetic cutout range Q3, and the thickness cutout range Q4 are set using PL4. Subsequently, the discrimination control unit 41 generates the cut-down information T1, the cut-up information T2, the cut-out magnetic information T3, and the cut-out thickness information T4 by cutting out these ranges, and these are stored in the discrimination storage unit 42. Are stored in the reject banknote information storage area.

For this reason, the automatic teller machine 1 has the cut-down information T1, the cut-up information T2, the cut-out magnetic information T3 and the cut-out magnetic information T3 centered on the portion corresponding to the bill on the reject banknote information display screen D1 (FIG. 9). Images based on the cutout thickness information T4 can be displayed side by side vertically and horizontally so that their positions correspond to each other. Thereby, the automatic teller machine 1 can make the staff etc. who looked at this reject banknote information display screen D1 easily guess the reason that the banknote was determined to be abnormal, and can further explain to the customer.

In particular, in the discrimination unit 24 (FIG. 4), the thickness sensor 33, the upper image sensor 35A, and the lower image sensor are disposed at locations separated from each other in the front-rear direction along the banknote transport path W in order to arrange them based on the characteristics of each sensor. 35B and the magnetic sensor 37 are located respectively. For this reason, even if each information obtained from each sensor arrange | positions the produced | generated time temporarily, the part corresponded to a banknote is mutually different, and the comparison operation by the staff etc. is not easy.

In order to deal with this problem, the discrimination unit 24 stores the relative distances between the sensors in advance, and cuts out the ranges that differ from each distance from the information obtained from the sensors, thereby making it possible to The portions corresponding to the same location can be stored in a state where they are aligned (FIG. 8).

Further, in the discrimination unit 24, the rotation amount of the motor 39 counted as the number of pulses by the encoder 39E and the conveyance distance of banknotes by the conveyance roller pair 32 rotated by the driving force from the motor 39 are in a proportional relationship. Further, each time the pulse count value increases, the discrimination unit 24 stores information for one line (lower image information, upper image information, magnetic information, and thickness information) newly obtained from each sensor in each information storage area. Store. For this reason, in the discrimination part 24, the address of each information storage area | region and the pulse count value, ie, the conveyance distance of the banknote in the conveyance path W, respond | correspond.

Therefore, the discrimination unit 24 adds or subtracts only the pulse count value corresponding to the distance of each sensor from the address in the range corresponding to the banknote in the lower image information storage area 51, so that the banknote is transferred to the banknote in the other information storage areas. An address representing a corresponding range can be easily calculated. Further, since the discrimination unit 24 converts the distances L2 to L4 into pulse distances PL2 to PL4 in advance and stores them in the discrimination storage unit 42, multiplication or division is not required when calculating an address, and only simple addition or calculation is performed. Just do it.

By the way, in thickness information and magnetic information, the horizontal shape of the thickness sensor 33 is relatively low, and the portion where the magnetic ink is used for the banknote is limited, so that the outline of the banknote does not necessarily appear clearly. There was no case. Therefore, the discrimination unit 24 first recognizes the banknote area and each vertex in the lower image information stored in the lower image information storage area 51, and first sets the lower image cutout range Q1 in the lower image information. The magnetic cutout range Q3 and the thickness cutout range Q4 are set by adding or subtracting the addresses. Thereby, the discrimination part 24 can cut out appropriately the thickness information and magnetic information of the part corresponding to the range which has recognized the banknote as an image, ie, the range where the possibility that a banknote exists is very high.

According to the above configuration, the automatic teller machine 1 first sets the lower image cutout range Q1 in the lower image information storage area 51 when there is a banknote determined to be abnormal by the discrimination unit 24 of the banknote depositing and dispensing machine 10. To do. Subsequently, the automatic teller machine 1 adds the upper image cutout range Q2, the magnetic information to the addresses obtained by adding or subtracting the pulse distances PL2 to PL4 respectively in the upper image information storage area 52, the magnetic information storage area 53, and the thickness information storage area 54. A cutting range Q3 and a thickness cutting range Q4 are set. As a result, the automatic teller machine 1 can generate cut-out information T1, cut-out information T2, cut-out magnetic information T3, and cut-out thickness information T4 in which the corresponding parts of the bill are cut out, and reject them. By displaying the information on the information display screen D1 (FIG. 9), it is possible for the staff or the like to easily guess the reason that the banknote is determined to be abnormal.
